摘要
传统支气管镜检查对周围性肺部疾病的诊断较为困难，通过透视或超声引导肺活检的确诊率也较低；螺旋CT仿真支气管镜虽能发现腔内病变，却无法取得病理学、细胞学或病原学诊断。电磁导航支气管镜将两者的优点结合，通过螺旋CT和电磁导航设备使活检器械等可以准确到达周围肺组织或纵隔淋巴结并取得活检，确诊率明显高于传统支气管镜检查，为支气管镜诊断周围性肺部疾病和纵隔疾病提供了新的方法。
Peripheral lung lesions are often the blind zone to the conventional flexible bronchoscopy.Although by the guidance of fluoroscopy and ultrasound, the accuracy of biopsy in the target area is not satisfied. Spiral CT virtual broncoscopy can only detect the location of the lesions but the pathological or cytological diagnosis can not be available. The new bronchoscopy technique that allows an approach to the peripheral lung masses is electromagnetic navigation based on virtual bronchoscopy and real-time threedimensional （3D） CT images. This technique has been shown to be capable of reaching peripheral lung masses and mediastinal lymph nodes beyond the reach of the standard bronchoscopy, which increases the diagnostic yield of the transbronchial biopsies in the primary clinical trails.
